Virtual Basic Laparoscopic Skills Trainer (VBLaST) is a virtual reality trainer that replicates the Fundamentals of Laparoscopic Surgery (FLS) tasks for training in minimally invasive surgery. For the ligation loop task, we have developed a novel hardware interface using a linear motion stroke potentiometer to accurately sense the linear translation of the ligation loop and a mechanism to attach the tool interface to a PHANToM Omni for force feedback. Testing shows that the interface provided a realistic feel and control of the loop similar to the endoloop device used in FLS ligation loop task.

Unlabelled: are facultative intracellular bacterial pathogens that cause foodborne disease in humans. The bacteria can use the surface protein InlA to invade intestinal epithelial cells or transcytose across M cells in the gut, but it is not well understood how the bacteria traffic from the underlying lamina propria to the draining mesenteric lymph nodes (MLN). Previous studies indicated that associated with both monocytes and dendritic cells in the intestinal lamina propria.

Article Synopsis
- Metastasis is a complicated disease that relies on specific protein interactions, such as Vimentin and NEDD9, which are crucial for cancer progression and treatment resistance.
- Withaferin A (WFA) is a natural compound thought to target Vimentin, potentially offering a way to inhibit metastasis, although its complete mechanism is still not clear.
- Research has utilized various techniques, including gene expression analysis and protein interaction assays, to demonstrate that targeting the Vimentin-NEDD9 interaction with WFA can reduce melanoma spread to the lungs, highlighting its potential as a therapeutic approach.

Article Synopsis
- N-methyladenosine (mA) is a common RNA modification that significantly impacts various biological processes and human health, but its functions are not fully understood due to difficulties in measuring it accurately.* -
- The study developed a new technique that enhances the ability to distinguish between mA and regular adenosine (A) by up to 265 times, using a combination of polymerase and ligase selectivity methods.* -
- This innovative assay employs ligation-based loop-mediated isothermal amplification (LAMP) to achieve extremely high sensitivity, enabling the detection of RNA at concentrations as low as 40 aM and allowing for precise quantification of mA at a single nucleotide level.*

The prebiotic formation of RNA building blocks is well-supported experimentally, yet the emergence of sequence- and structure-specific RNA oligomers is generally attributed to biological selection via Darwinian evolution rather than prebiotic chemical selectivity. In this study, we used deep sequencing to investigate the partitioning of randomized RNA overhangs into ligated products by either splinted ligation or loop-closing ligation. Comprehensive sequence-reactivity profiles revealed that loop-closing ligation preferentially yields hairpin structures with loop sequences UNNG, CNNG, and GNNA (where N represents A, C, G, or U) under competing conditions.

Introduction: Considering the effective treatment of postpartum hemorrhage, intrauterine balloon tamponed can apply pressure from the inside of the uterus, and uterine compression suture can apply pressure from the outside of the uterus. Although combining the two methods can enhance the effectiveness of hemostasis, there is a paucity of studies reporting on outcome. The aim of this study was to report a surgical protocol for postpartum hemorrhage by intrauterine balloon tamponing combined with mid-section loop ligation and its subsequent effects on the uterus.
